npm install failing to run due to what seems to be an environment variable error

Question

I get the below error when I try to run npm install. I believe I successfully ran this without issue for another application.

npm install

This current application contains a .npmrc file but I also have it in my users folder. I thought there may be a conflict there but it doesn't seem to be the case. How do I resolve this?
